It's a few days later when the Ambassador walks into the laboratory, their skin is flushed and they look uncomfortable over the whole situation. "Perceptor, can you run some tests for me? I came into contact with one for the flowers Traxies has, he's finally opened up and I was chatting with him and he was showing some of the flowers he has, and I think I'm having an allergic reaction to it" they call out while moving closer as both Brainstorm and Perceptor watch them.

"Christ I feel like I'm burning up and it's too hot in here" they huff out while climbing the stairs up onto the table. Preceptor's field immediately flared with concern as the ambassador entered the laboratory, their flushed complexion and strained voice instantly catching his attention. His cooling fans kicked into a low hum as he stepped forward, his optic scanning the ambassador with a practiced precision. As he presses a digit to their forehead. "An allergic reaction, you say?" Perceptor murmured, his tone calm but laced with urgency. He gestured toward a nearby diagnostic bench. "Please, take a seat here. We shall run the necessary tests to determine the extent of your reaction."

Brainstorm, on the other hand, was already leaning forward from his workstation, his optics narrowing as he observed their clearly distressed state. curiosity and unease, though a faint flicker of something else lingered just beneath his optics. "Burning up, huh?" the engineer remarked, his voice tinged with a hint of intrigue. Both mechs involuntarily stiffened, their sensory arrays picking up on the subtle but unmistakable spike in their hormone levels. The scent hit their olfactory sensors like a jolt.

Perceptor's vocalizer clicked faintly as he focused on maintaining his composure. "I must ask," he began, his tone measured, though his field betrayed a faint ripple of unease, "was this flower one of the specimens Traxies recently acquired? If so, it may possess properties we have yet to fully document. He tend to bring back a large variety of them from expedition" His servo hesitated briefly before gesturing toward the scanner. "I will need a sample of your blood to confirm the presence of any allergens or foreign compounds."

The ambassador nodded, their discomfort evident as they sank onto the diagnostic bench. " I didn't think much of it at first, but now I feel like my body’s on fire," they muttered, their voice strained as they pull at their collar trying to cool doen their body temperature. They glanced between the two mechs, their flustered expression deepening as they noticed the subtle hum of their cooling fans. "And why is it so damn hot in here?, I thought the laboratory was cold, Is it just me?"

Brainstorm makes an awkward static buzz, his optics darting toward Perceptor before quickly looking away. "Uh, nope, definitely not just you. I mean, it's warm here, but, uh..." He trailed off as he tried to focus on the readouts rather than the ambassador's flushed appearance. Perceptor shot Brainstorm a warning glance, his field rippling with a subtle reprimand towards the other scientist before he turned his attention back to the ambassador. "If the flower does indeed contain an unknown compound, it may be inducing a reaction within your system that requires immediate attention."

As Perceptor takes a quick blood sample, his optic flickered with faint unease. The scent in the air was undeniably affecting his systems, even as he fought to suppress the distracting signals flashing on his Hud. though a subtle warmth crept into the edges of his frame. Beside him, Brainstorm fidgeted, his cooling fans audibly kicking into a higher gear as he struggled to focus on the task at hand.

"Right," Brainstorm said, breaking the tense silence. "So, uh, if this is some kinda weird alien aphrodisiac thing because I can currently see every atom and molecule of their scent right now and my sensors are blaring with warnings and notifications." His optics darted back to the ambassador, his field pulsing with barely concealed apprehension. "Not that I’m saying that’s what’s happening or anything! Just, uh, covering all the bases." Preceptor's field flared with a sharp pulse of exasperation, though his voice remained calm. "Brainstorm, please refrain from such crash terms. The priority is ensuring the ambassador's safety, not indulging in baseless hypotheses."

The ambassador, still visibly flustered, let out a soft groan as they leaned back against the bench. "I don’t care what it is—just fix it. I feel like I’m gonna combust if this keeps up," they muttered, their voice tinged with desperation. Preceptor's optic softened slightly, his voice gentle with reassurance. "We will resolve this, ambassador. Rest assured, you are in capable hands."

As the scans begin, both mechs work in tense silence, their fields betraying their mutual determination to stay focused despite the distracting scent lingering in the air. It was clear that the situation was affecting them both, their systems struggling to suppress the reactions triggered by the ambassador's elevated hormone levels.

As the two scientists work their optics flick back to the Ambassador to check on them, they are sprawled across one of the medical benches in the lab half their uniform discarded as they fan themself trying their best to lessen how hot they feel, the cold surface of the table helped. "Please tell me you guys have found something?" They ask eyes fluttering open to look at the two mechs, the Ambassador nearly whines at how cold Brainstorms servo feels against Their flustered skin when he comes over to check them.

Perceptor cleared his vocalizer with a faint click, his optic narrowing as he focused on the scanner's readouts. "We are making progress," he assured, though his voice carried a slight strain. "The compound from the flower appears to contain a potent pheromone-like substance, one that our physiology is reacting to." Brainstorm’s servos twitched, his optics flickering with both concern and a barely concealed nervousness. "Yeah, uh, it’s kinda like an aphrodisiac, but cranked up to eleven, we don't have a cure for it" he added, his tone hovering somewhere between clinical and awkward. "It’s messing with your system pretty bad, huh?"

The ambassador let out a soft, frustrated groan, their head tipping back against the cold surface of the bench. "You think?" they muttered, their voice thick with discomfort as they fanned themselves with a loose sleeve. "I feel like I’m going to melt into this table. And whatever that flower did to me, it’s making everything feel a hundred times worse," they added, their gaze flickering toward Brainstorm as his servo brushed against their arm. A shiver ran through them at the coolness of his touch, and they let out a soft, involuntary whine. "God, your hands are freezing... Thank God."

Brainstorm froze for a moment, something between alarm and barely contained fascination flashes through his system. "Uh, yeah, well, y’know, mech servos are good for more than just tinkering," he said, trying for humor but failing to hide the nervous edge in his voice. Perceptor shot him a pointed glare, His voice softened slightly, his tone laced with a rare gentleness. "The cold surface will help mitigate your symptoms temporarily," he said, gesturing toward the bench. "However, until we can synthesize an antidote or at the very least, a suppressant we must ensure that you remain hydrated and as comfortable as possible."

The ambassador nodded faintly, though their breathing remained uneven, their flushed skin glistening faintly under the lab's artificial lights. "Comfortable, right," they murmured, their voice tinged with a mix of exasperation and helplessness. "I don’t think ‘comfortable’ is even possible right now."

" uh, Perce, how long do you think it’ll take to whip something up?" His voice trailed off as his optics flicked over the ambassador again, his field pulsing with barely concealed heat. "This doesn’t exactly look like something we can just wait out." Preceptor's optic narrowed as he focused on testing the blood samples with different chemicals in hopes of finding something that will dull the effects of the aphrodisiac, his servos working with practiced precision despite the distracting scent in the air. "If the compound's structure is as straightforward as it appears, I should be able to synthesize a suppressant within the next hour," he replied, his voice tight with concentration. His field pulsed with a subtle warmth, betraying his own struggle to maintain focus. "In the meantime, Brainstorm, ensure that the ambassador remains hydrated. Their elevated body temperature could lead to dehydration if left unchecked due to sweating."

Brainstorm blinked, his optics widening slightly as he processed the request. "R-right, hydration. Got it!" he stammered, quickly moving to retrieve a small bottle of water from the lab’s supplies. He returned to the ambassador’s side, his movements uncharacteristically cautious as he offered it to them. "Here, uh, drink this. It should help... a little, at least." The ambassador’s fingers brushed against Brainstorm’s digits as they took the water. "Thanks," the ambassador murmured, their voice soft and a little breathless as they took a sip. Their gaze lingered on Brainstorm for just a moment too long, and the mech’s optics flickered with a mixture of guilt and fascination.

The Ambassador presses themself back into brainstorm servo trying to get as much of the cold metal surface pressed against their body. A soft moan seems to leave their lips as Brainstorm let's his digits trace over their skin. "Please, it's too hot, your servos feel nice, don't feel like I'm burning" they mutter softly to Brainstorm.

Preceptor's frame stiffening as the scene before him unfolded. His optic flickered toward Brainstorm, who stood frozen, his optics wide and glowing faintly brighter as the ambassador pressed closer to him. Brainstorm’s field spiked with an overwhelming mix of arousal and hesitation, his digits twitching as the ambassador guided his servo between their thighs. The scent of their hormones, now impossibly potent, flooded his olfactory sensors, sending his cooling systems into overdrive. "Uh, I—" he stammered, his vocalizer glitching slightly as his optics darted to Perceptor for guidance. But the scientist, for once, seemed just as flustered as he was.

"Ambassador," Perceptor began, his voice strained as he tried to maintain some semblance of professionalism, "This… this reaction is a result of the flower’s compound. Your judgment may be… impaired." His optic flickered down to where the ambassador clung to Brainstorm, their flushed skin pressed against the cool metal of his servo trying desperately to grind against it. “yea well it feels like my body is melting and this makes it not feel as ablazed” the ambassador manages to call back at him.

"Not that I’m, uh, complaining or anything, but… are you sure this is what you want? I mean, you’re burning up, and—" He cut himself off with a sharp intake of air as the ambassador shifted, pressing closer.

Their voice, soft and pleading, sent a shiver through Brainstorm’s frame, his field pulsing with a heady mixture of arousal and concern. "Please, just help me " they murmured, their breath hitching as they guided his digits further as they fought with what's left of their clothings trying to get it off as quickly as possible. their flushed skin trembling at the coolness of his touch. "Stars, that feels amazing." They basically moan out.

Brainstorm hesitated only a moment longer before his digits began to move, tracing slow, deliberate patterns against their skin. "Look, Perce, they’re asking for help," he murmured, his voice low and tinged with a heat that matched his field. "And if this is what helps them feel better, then who are we to argue?" The ambassador let out a soft moan, their head tipping back as Brainstorm’s digits pressed more firmly against them. Their hands clung to his arm, body trembling as they sought out every inch of cool metal they could reach. "I'm giving you both my consent, please just help me with this," they whispered, their voice thick with relief and desire.

Finally, with a soft sigh of resignation, Perceptor stepped closer, "See, Perce? Teamwork," he said with a faint grin, though his voice trembled with the weight of his own desire. "We’ll have them feeling better in no time." His servos pull away making the Ambassador whine only for them to be replaced with Preceptor's. “Hush now” he hums while Brainstorm positions his faceplate between the ambassador’s thighs. They arches their back. The Ambassador’s breath hitched sharply, their back arching as Brainstorm's glossa dragged over their sensitive sex, his mouth enveloping them with agonizing slowness. His lips sealed around them, his movements slow as he studies and learns as he goes, savoring every reaction they give him. His digits traced a teasing path up their trembling thighs, the sharp edges of his servos sending shivers through their overstimulated body.

“Sweet Primus,” Brainstorm murmured against them, his voice muffled but laced with mischief and hunger. “You taste so good, Ambassador. I could do this all cycle.” He flicked his glossa over their most sensitive spot, eliciting a moan that made his optics brighten with delight. “Keep making those little sounds for me, won’t you? You sound divine like this.”

The Ambassador’s fingers clutched desperately at Preceptor's plating, their body writhing as the effects of the aphrodisiac heightened every sensation as Brainstorm's glossa teases them and works them into a state of bliss. Perceptor, ever the observer adjusted his grip on their waist to steady them, holding them open for Brainstorm and to make sure they don't hurt themself on any part of Brainstorm's helm. His digits moved with measured precision, gliding down their body in soothing strokes.

The Ambassador whimpered, their head falling back against Preceptor's servo and arm plate as his cool touch sent a wave of relief through their flushed body. they gasped, and buck against Brainstorm’s mouth, the dual sensations driving them closer to the edge.

Preceptor's optic softened, his digits brushing across their damp forehead. “You’re handling this remarkably well, considering the circumstances,” he murmured, his tone gentle as his digits pressed into a pressure point along their side.

“Wasn't expecting to get fuckin Sex pollened by a flower” the ambassador states trying to make a joke out of the situation only to gasp and cry out as Brainstorm's glossa presses I to them. “Oh fuck, oh fuck!” They moan out, eyes fluttering closed. Brainstorm’s digits dug lightly into their thighs, holding them in place as he worked. “Brainstorm,” Perceptor chided lightly, though his own digits slid lower, tracing the curve of the Ambassador’s hip as he leaned closer to press his lips to their temple. “We’re here to help them, not overwhelm them.”

“Oh, I’m helping,” Brainstorm retorted with a grin, his glossa pressing firmly against their most sensitive spot before pulling back slightly. “Tell him, Ambassador. Tell Perce how good I’m making you feel.” Their hips jerked against Brainstorm’s mouth as their hands clutched at Preceptor's arms for support. “don't stop, please don’t stop,” they stammered, their words barely coherent as their body quaked between the two mechs.

Brainstorm hummed in satisfaction, his mouth redoubling its efforts as his servos spread their thighs wider, giving him better access. The Ambassador’s trembling hands gripped the back of Brainstorm’s helm, their fingers tangling in the delicate grooves as they tried to pull him closer, desperate to feel more of the overwhelming pleasure he was giving them with each flick of his glossa. Their body shuddered uncontrollably beneath him, hips jerking in time with the teasing, deliberate movements of his glossa. Little mewls and whines spilled from their lips, each sound betraying just how much they were unraveling between the two mechs.

The Ambassador whimpered softly, pressing themselves closer to Preceptor's solid frame, their trembling body seeking refuge. “P-Perceptor…” they gasped, their voice breaking as their hips instinctively bucked against Brainstorm’s mouth. “It’s so much... I can’t—” “You can,” Perceptor interrupted softly, his tone a perfect mix of reassurance and command. tilting their head slightly so their flushed face was angled up toward him. “Focus on me. Breathe. We’ll take care of you.”

Brainstorm let out a low chuckle, “You’re doing so good,” he murmured, his voice dripping with praise and satisfaction. The Ambassador’s fingers tightened on Brainstorm’s helm, a strangled cry escaping their throat as his glossa drove harder into them teasing their most sensitive spot. Their eyes fluttered shut for a moment before snapping back open. “Oh God Brainstorm!” they cry out basically rutting against his mouth as they sob, before going limp in Preceptor's servos.

When Brainstorm finally pulled away, his lips plate glistening and his expression smug with satisfaction, the Ambassador’s trembling form clung to Perceptor for support. Their chest heaved with uneven breaths, their flushed face pressed against the scientist's plating as they tried to steady themselves. But Preceptor's optic never left them. “You’re doing remarkably well,” Perceptor murmured, his voice as calm and soothing as ever, despite the slight static crackle betraying his own restraint. One servo rested lightly on their hip, grounding them, while the other shifted lower.

The Ambassador whimpered softly, their body still quivering from Brainstorm’s ministrations, but they didn’t resist as Preceptor's digits ghosted between their thighs. The cold touch of his metal sent a sharp shiver through their overheated body, a stark contrast that made them inhale sharply. “Easy,” Perceptor murmured, his tone gentle as his digit dragged slowly between their thighs, his movements deliberate as he searched for what he was looking for. “I need you to stay relaxed. This will be much easier if you trust me.”

“You’re doing amazing, Ambassador. Just let him take care of you.” Brainstorm states as he presses a kiss to their thigh. Perceptor ignored Brainstorm’s commentary, his focus entirely on the Ambassador as his digit finally found what he was seeking. He paused, his optics flickering up to meet their tear-filled gaze. “There,” he said softly, almost to himself, as if confirming a calculation. “Now... this may feel a bit intense. Tell me if it’s too much.” With the utmost care, Perceptor pressed the tip of his digit against them, his movements painstakingly slow as he began to ease it inside.

The Ambassador’s breath hitched, a choked sound escaping their lips as the coolness of his metal sent a wave of bliss crashing through their body. They nearly sobbed at the sensation, their hands clutching desperately at Preceptor's arm plate as their head tilted back. “P-Perceptor,” they gasped, their voice trembling as tears pricked at the corners of their eyes. “Shh,” he soothed, his free hand moving to cradle the back of their head as his digit pressed deeper, careful and deliberate. “You’re doing wonderfully. Just focus on your breathing. I’ll take care of the rest.” His tone was clinical yet impossibly tender, treating the Ambassador as if they were the most delicate thing in the universe.

Brainstorm let out a low hum of approval, his optics narrowing as he leaned closer to watch Preceptor's precise movements, watching the way his digit disappeared into the ambassador before reappearing. “See? I told you he’s good with his servos,” he quipped, though his voice was softer now, lacking its usual sharp edge. The Ambassador sobbed softly, their body trembling as Preceptor's digit moved inside them, the smooth, cold metal easing the unbearable heat that had consumed them.

The Ambassador could only nod weakly, their body trembling with each deliberate stroke. “You’ve got them practically falling apart, Perce,” he said, his voice low and amused. The Ambassador’s cries grew softer, their body sagging against Perceptor as the overwhelming sensations began to blur into a haze of bliss. With each careful motion of his digit, the heat that had consumed them began to ebb away, replaced by a soothing coolness that left them trembling and utterly pliant in his arms.

“You’re doing so well,” Perceptor murmured, his voice soft and reassuring as his free servo stroked their back in slow, calming circles. “Just a little longer, and we’ll have you feeling like yourself again.” The Ambassador whimpered softly, their fingers clutching at Preceptor's plating as they nodded, their trust in both mechs absolute. needy whimpers escaped their lips. Preceptor's digit continued its slow, deliberate movements, each stroke carefully calculated.

The Ambassador gasped sharply, their body jolting at the curl of Preceptor's digit; the sensation had them rocking back against Preceptor's servo. The Ambassador’s head tilted back, their eyes fluttering shut as their body arched instinctively toward the dual sensations. Preceptor's slow, precise movements inside them and Brainstorm’s teasing kisses along their thighs sent their mind spiraling, each touch feeding the fire that burned within them. “Brainstorm… Perceptor…” they whimpered.

The Ambassador’s body tensed suddenly, their breath catching in their throat as the overwhelming sensations reached their peak. A broken cry escaped their lips, their back arching as the pleasure crashed over them in waves, leaving them trembling and writhing in the arms of the two mechs.

Perceptor was the first to react, his optics brightening as he registered the shift in their body. His digit stilled inside them, holding steady as he allowed the Ambassador to ride out the intense sensations without overwhelming them further. His free servo pressed gently against their lower back, supporting their quivering frame as he murmured soothingly, “There... that’s it, Ambassador.”

Brainstorm, on the other hand, was anything but restrained. A low, satisfied growl rumbled from his vocalizer as he watched the Ambassador tremble and cry out, their body convulsing with the intensity of their climax. “Primus,” he muttered, his optics flashing with a mixture of pride and arousal. “Look at you. You’re absolutely beautiful like this.”

He leaned in, his lips brushing over the Ambassador’s thigh as his hands gripped their hips, steadying them as their body shook. The Ambassador whimpered softly, their hands clutching weakly at Preceptor's plating as they rode out the last waves of their climax. Tears streaked their flushed face, their body utterly spent yet still trembling from the aftershocks.

Perceptor carefully withdrew his digit from them, his movements slow and deliberate to avoid overstimulating their already sensitive body. He gently adjusted their position in his arms, cradling them against his frame as his servo moved to stroke their back in soothing circles. “You did exceptionally well,” he said softly, his voice filled with quiet pride.

Brainstorm sat back slightly, his servos still resting on the Ambassador’s hips as he looked up at them with a wide grin. “That was more than remarkable, Perce. They were absolutely breathtaking.” The Ambassador let out a soft, breathless laugh, their body slumping against Preceptor's as the last remnants of their climax faded. “you two are fuckin fiends,” they murmured, their voice shaky but filled with gratitude. “Thank you...”

Preceptor's optics softened, his servo cupping the side of their face as he gazed down at them with quiet affection. “There’s no need to thank us,” he said, his tone gentle. “It was our privilege to assist you.” Brainstorm chuckled, his grin widening as he leaned in to press a soft kiss to the Ambassador’s temple. “You’re welcome, sweetheart. Anytime you need us, you know where to find us.” He winked, his tone playful but sincere as he added, “And next time, maybe don't get yourself dosed up by an Aphrodisiac flower. Sounds good?” The Ambassador blushed deeply, their face burying itself in Preceptor's plating as they let out a soft laugh.
